CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 290,434, dated December 18, 1883.

Application filed September 29, 1883. (No model.)

.To aZZ whom it may concern:

Be it known that I, ADAM KEIL, of Monongahela City, in the county of Washington and, State of Pennsylvania, have invented certain new and useful Improvements in Car lVheels and Axles, of which the following is a specification, reference being had to the accompanying drawings.

The object of my invention is to provide for the convenient lubrication of the journals of car-wheels which run loosely upon their axles, and to prevent the ingress of dirt, dust, and other obstructions to the journal.

In the accompanying drawings, Figure 1 is a sectional view of a car wheel, axle, and oilbox, drawn .on line 1 1 of Fig. 4. Fig. 2 is a section through the wheel and axle on the line 2 2 of Fig. 4. Fig. 3 is a section on line 3 3 of Fig. 1, and Fig. 4 is a similar section on line 4 4. of Fig. 2.

A indicates the car-wheel, B the axle, and G a cap cast upon or otherwise secured upon the outer face of the car-wheel, so as to be oil-tight. This cap is provided with an oilopening, D, suitable to admit of oil from the spout of an oil-can into. the oil cup or recess D, opposite the outer end of the journal.

At the inner side of the car-wheel, E indicates a fixed collar on the axle.

L indicates anoil-passage extending from the outer end of the axle into the body of the car-wheel obliquely with respect to the axle, where it meets a similar oil-passage, L, which extends obliquely from the inner endof the journal into the body of the car-wheel. At the angle where these two passages meet, within the car-wheel body, is an oil-passage, M, .which communicates diametrically with the journal. There may be four sets of these oil-passages, or.more or less, but four are sufficient, and are recommended.

N indicates an ani'lular space cast in the interior of the hub, at the inner end of the j ournal, to connect the oil-passages with one another, to permit the free fiow of oil from one set of passages to another, and to distribute it freely over all parts of the surface of the journal. The oil-opening D may be provided From this construction it will appear that when the stopper is open and oil is poured into the oil-opening D it will fill the oil-passages which happen to'be beneath, and thus a large supply of oil may be stored. When the car-wheel is set'in motion, it will deliver the oil out of the lower passages upon the journal, where it will be distributed, and during the revolutions of the wheel will be constantly flowing in and out of the oil-passages by the force of gravity. This method of lubricating is well adapted to car-wheels or other wheels, because the inclination of the oil-passages L L directs the oil by the force of gravity to the center of the axle. This is an advantage which the inclined passages have over horizontal passages which have heretofore been used, and the inclined passages L L and the radial passage M form a considerable reservoir for oil whenever the wheel is at rest.

I have designed my improvements above described so that it will, be practicable to readily apply them to cars of the common pattern already in use by merely removing theold wheels and putting on my improved lubricating wheels, and providing annular grooves in the outer ends of the axle-journals for the linchpins.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States. is

1. The combination, with a car-wheel, A, loose upon an axle, B, of an oil-tight cap, 0, provided with a central oil-opening, D, and oil-cupD, an oil-recess, N, and two or more sets of oil-passages, L L and M, at angles to and communicating with each other, substantially as and for the purpose set forth.

2. The combination, with a car-wheel, A, loose upon its axleB, of the cap 0, the oilrecesses D and N, and the oil-passages L L and M, all communicating with each other, the linchpins, the annular groove in the axle, and the fixed collar E, substantially as set forth.

In testimony whereof I have hereunto subscribed my name this 24th day of September A. D. 1883.

ADAM KEIL.
